The industry owned trawlers land-lock obligation, originally intended to ensure both greater seasonal distribution of raw material as well as settlement in coastal communities, functions poorly and is being put under pressure. This is due to national and global trends in economics and politics, technological change and changing market conditions....
Marine protected areas (MPAs) have become a widely used tool for marine conservation and fisheries management. In coastal areas, it has become clear that the success of MPAs, and the achievement of sustainable fishery production, requires a combination of effective management and conservation frameworks, maintenance of decent fisheries livelihoods, and...
The study focused on the production of Clarias gariepinus fingerlings produced from Clarias gariepinus broodstock fed inclusion levels of Azanza garckeana. Clarias gariepinus broodstock fed different inclusion levels (0, 5, 10, 15 and 20%) of Azanza garckeana pulp meal, representing diet 1, 2, 3, 4 and 5 in a randomised...
Salmon aquaculture is constrained by the proliferation of salmon lice, a natural seawater parasite that benefits from the agglomeration of production. The lice challenge currently costs the Norwegian salmon farming industry above 450 million USD per year (0.5 USD/kilo). Adjacent farms impose a contamination externality on each other, which they...
The food security situation in Latin American and Caribbean countries is very diverse, and even more when special attention is given to the seafood sector. The latter contributes both directly and indirectly to household and national food security, providing food, employment and income generation, among other benefits. This survey aims...
Eco-certification of seafood has been suggested to be a key market based mechanism for reducing the pressure on the world’s aquatic ecosystems. In the study presented here we investigate to what extent consumers’ stated purchasing of eco-labelled seafood was correlated with seven internal variables: environmental knowledge, familiarity with eco-labels, subjective...
For decades, fishing was considered an area warranting public support policies, particularly its industrial segment. The sector continues to enjoy the support of international donors in addition to significant private overinvestment. Globally, catches of artisanal fisheries continue to grow while industrial fisheries decline since the mid 1990s. The latter are...
The study examined Fish Value Chain (FVC) in Yola area of Adamawa state, Nigeria. Primary data were collected using questionnaire and were analysed using descriptive and inferential statistics. The results showed that female dominate the fish marketing and processing nodes with 79% and 62% respectively while male (77%) dominate the...
Poverty issues cannot be underestimated in fish farmers' production as they influence farmers' attitudes towards risk. Despite the fact that there are studies on fish production risks, there is little or no study on fish farmers' poverty status and risk attitudes nexus in Nigeria. Hence, this study examined risk attitudes...
As the Scottish enlightenment has taught us, it is vitally important to think for ourselves rather than believing what we are told. Here, we question the basic principles of fisheries managements. We ask if the hypothesis of capacity maximization - a race to boats - could be considered instead of...
The Alaska non-pollock multi-species catcher processor trawl fishery, referred to as the Amendment 80 fishery since 2008, is an endlessly fascinating subject from the perspective of an economist. A diverse group of companies and vessels, emphasizing different species mixes from a multi-species ecosystem, targets fish across the Eastern Bering Sea,...
Assessment studies have summarized the literature on global food security and projected impacts of climate and other major drivers of regional and global change in the 21st Century (IPCC, USDA). Additionally, the Agricultural Model Inter-comparison and Improvement Project (AgMIP) is working to develop new coordinated global and regional assessments of...
The Northwest Fisheries Science Center has been collecting cost earnings data since 2003. The Center economists survey all commercial fishing vessels on the West Coast of the United States from San Diego, CA to Blaine, WA. These vessels range in size from less than 40 feet to more than 300...
Trust is a key aspect in managing fisheries. Individuals with low levels of political trust are more likely to accept illegal behavior. Institutional trust depends on beliefs about institutional behavior and on how competent an institution appears to be. The success of fisheries management depends on how fishermen perceive it....
Traditional approaches to halt decline of fisheries resources focus on regulating against destructive practices, but to little effect. A more effective strategy could be to establish a direct economic incentive mechanism such as payments or compensation schemes, or to incorporate such payments into existing regulatory mechanisms. Examples from terrestrial environments,...
Bargaining power has in many fisheries shifted considerably from fish processors to fishermen with modern communications, higher fleet mobility and increased scarcity of the resources. In Norway, fishermen were to a large degree exploited by processors up until the early 20th century. A strong collaborative effort from the fishermens' union...
The presentation summarizes preliminary results of the first part in the PhD project “Economic valuation of the wild salmon stock in Norway”. The externalities from the salmon farming industry, such as spread of parasites and genetic pollution, affect wild salmon populations. The aquaculture management in Norway faces a trade-off between...
The concept of shared value has been defined by Porter and Cramer as those policies and operating practices that enhance the competitiveness of a company while simultaneously advancing the economic and social conditions in the communities in which it operates. This concept guides a coordinated process of stakeholders' engagement to...
This presentation provides an overview of a Special Session presentation held at the IIFET 2016 Scotland conference in July 2016. The registration number and title of the special session were 5024: Game Theory and Fisheries. The session was organized by Marko Lindroos.
The introduction of private property rights in common pool resource systems is not occurring at random, but depends on various factors, including the state of the resource itself. This inherent endogeneity problem of policy implementation makes it difficult to make any causal inference between the regulatory regime and the state...
This presentation provides an overview of a Special Session presentation held at the IIFET 2016 Scotland conference in July 2016, as well as details of the proceedings of the session.
Tilapia is the world's most popular aquaculture species farmed mostly in earthen ponds. Experience in China (the largest tilapia farming country) is used to develop and calibrate a bio-economic model on intensive tilapia pond culture. The model is used to simulate the impacts of climate, technical and/or financial factors on...
Different user groups have different stakes in fisheries. The societal challenge is that, exploiting the same fish stock, or ecologically interacting stocks, recreational and customary fishermen interact with a continuum of commercial fishermen, ranging from very small-scale and part-time artisanal fishermen to large-scale fishing firms. In this paper we develop...
Pole-and-line and hand-line tuna fisheries, hereafter referred to as one-by-one fisheries are believed to provide large social benefits to fishing communities. Unlike industrial high seas fishing, large numbers of fishing vessels are involved - engaging many people from coastal communities. In the unique case of the Maldives, where fishing communities...
Irregular consumption of animal protein has been a problem confronting resource poor rural households in Oyo State. This study therefore investigated determinants of rural household demand for fish in Oyo State, Nigeria. Multistage sampling procedure was used. Ten Local Government Areas (LGAs) were purposively selected. Five LGAs were selected adjacent...

Lake Nasser extends for more than 300 km inside Egypt`s border and has an extensive shoreline of around 7000 km. It is an important source of fish for residents of Aswan and adjacent governorates in Upper Egypt, representing 55% of the total production from inland lakes in Egypt in 2013....
As part of the project ‘Building Food Security and Managing Risks: A Focus on Southeast Asia”, the OECD is examining how the fisheries and aquaculture sectors in Indonesia can better contribute to food security through improved policies. This paper examines the nature of the food security problem in the two...
Using stock assessments to inform management and decision makers about the impacts of fishing is increasing worldwide. Stock assessments are costly to conduct well, and there is often a data management lag in terms of when data used to inform stock assessment predictions are available for inclusion in the model....
The purpose of this paper is not to present new game theoretic results, but is rather to discuss a new and much needed research program, which is at an early stage. Progress to date will be reported upon. It is the contention of the authors that, in stark contrast to...
In June 2015, the UN General Assembly mandated the negotiation of a legally binding instrument on the conservation and sustainable use of marine biodiversity in areas beyond national jurisdiction (ABNJ). The proposed ABNJ Implementation Agreement (ABNJ IA) will have implications for the conduct and regulation of high seas fisheries and...
Despite an extensive literature on food-sharing, little attention has been given to the practice in the context of fish harvesting and consumption. We examine it as a possible, almost inadvertent, source of fishery management and we examine its role in trade. Our model is a simple general-equilibrium model of a small costal economy...
After half a century of fisheries development focused on large-scale fisheries the policy arena is finally becoming more conductive to sustaining small-scale fisheries (SSF) in economically developing countries, with a particular focus on international trade opportunities. Debates for and against increased integration of SSF into globalized trade have been presented,...
Infectious diseases continue to affect the productivity, efficiency, and consumer confidence of the aquaculture industry. This suggests that disease control remains an important area for further policy development. At the same time and contrary to terrestrial livestock enterprises, where economic incentive mechanisms have been proposed to influence behaviour change in...
